Dorman 594-589 Engine Harmonic Balancer

Dorman 594-589 Harmonic Balancer

Dorman 594-589 is a direct replacement engine harmonic balancer built for Ford Mustang, Ford F-150, and Lincoln Mark LT applications from 2011-2014. It uses a stress-resistant rubber bond to help absorb engine vibration and support smoother engine operation.

Key Features

• Direct replacement harmonic balancer for OE-style fit and function
• Stress-resistant rubber bond helps absorb crankshaft vibration
• Steel construction for durability in engine bay conditions
• Black finish
• Serpentine belt drive design with 10 pulley grooves
• Keyway type: yes
• Part number: 594-589

Detailed Description

This Dorman harmonic balancer is engineered for engines that need reliable vibration damping at the crankshaft. The bonded rubber element helps isolate torsional vibration, while the steel body is built to meet stringent tensile and impact strength standards for long-term service. If you are replacing a worn crankshaft balancer on a 2011-2014 Ford Mustang, 2011-2013 Ford F-150, or 2011-2013 Lincoln Mark LT, 594-589 provides a standard replacement solution with the correct serpentine belt configuration.

This part cross-references PowerBond by Dayco PB1638N and Schaeffler 102361 for the same application.

What It Helps Address

• Crankshaft vibration felt through the engine
• Worn or deteriorated harmonic balancer rubber bond
• Noise from a failing front engine pulley assembly
• Drive belt tracking issues related to balancer wear
• Replacement needs on Ford Mustang, Ford F-150, and Lincoln Mark LT engines

Installation Notes and Tips

Verify pulley groove count, inside diameter, outside diameter, and mounting dimensions before installation. Inspect the crankshaft snout, keyway, and surrounding front engine components for wear or damage before fitting the new balancer. Use the correct service procedure and torque specifications for the engine platform to ensure proper alignment and retention.

Quality Assurance

Dorman builds this harmonic balancer to meet stringent standards for tensile and impact strength, with a rubber bond selected to resist stress and support vibration control. Part number 594-589 is a standard replacement component for the listed Ford and Lincoln applications.
